The slope is the number in front of the x when y is on the side by itself.
Slope = -1/2
Answer:
The area of half of the garden in square meters
Step-by-step explanation:
Replace P with 15:
d = -3(15)^2 + 168(15) - 315
d = -3(225) + 2520 - 315
d = -675 + 2520 -315
d = 1530
45+5.25n>108
-45 -45
————————
5.25n > 63
Divide both sides by 5.25
n>12
